Canon - 70-200 F2.8 L IS USM
This is a spectacular professional lens: Here's some verbiage direct from Canon.....combining the virtues of the legendary EF 70-200 f/2.8L with the Canon's newest Image Stabilization technology. The IS system now offers up to a threestop improvement in hand-held ability, responds faster than ever before, and functions on a solid tripod. Additional improvements include faster AF response and tracking speed, weather-resistant construction, and the entirely new optical system focuses even closer (to 4.6 feet/ 1.4m) than the non-IS version. Incorporating Canon's second generation Image Stabilization technology, this telephoto zoom responds in as little at 0.5 seconds, while providing up to three stops of correction for camera shake. Its AF system has been refined for better response time and tracking speed. And even the new 8-blade circular aperture offers a more pleasing out-of-focus image. Constructed to pro standards, this fast zoom is also highly resistant to dust and moisture, too. Compact L- series zoom lens with an Image Stabilizer Compact, lightweight, high-performance L-series Telephoto zoom lens Flourite and Super UD elements enhance image quality Minimum focusing distance of 4.6 ft. at all focal lengths Ring USM for high-speed, silent AF with full-time manual focus Compatible with EF 1.4x and EF 2x Extenders Back to Top Focal Length: 70-200mm Maximum Aperture: 1:2.8 Lens Construction: 23 elements in 18 groups Diagonal Angle of View: 34 - 12 degrees Focus Adjustment: Inner focusing system with USM Closest Focusing Distance: 4.3ft. / 1.3m Zoom System: Rotating type Filter Size: 77mm Dimesions: width 3.4 length 7.8 in.

If you're impressed with all that technical stuff buy one....if you want my opinion...buy one. I rely on this lens every day, it's really a sweet piece of glass. The only complaint I have is that the image stabilization on-off and mode buttons and focus limiting switch are positioned such that if you use top loading bags, or if you inadvertently grab the lens in the wrong place you can easily move the buttons. I have mine taped in place so that they don't move unless I remove the tape and move the button. If Canon fixes this problem, they will have finally listened to me and about a thousand other people who have been complaining.
